Get the data copied to this class, before calling application handler.
Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |
|
|
This is the ACT associated with the handle on which the Asynch_Operation takes place. @ This is not implemented for POSIX4 platforms. Reimplemented from ACE_POSIX_Asynch_Result. Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |
|
|
Error value if the operation fail.
Reimplemented from ACE_POSIX_Asynch_Result. Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |
|
|
This returns ACE_INVALID_HANDLE.
Reimplemented from ACE_POSIX_Asynch_Result. Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |
|
|
I/O handle used for reading.
Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |
|
|
Message block which contains the read data.
Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |
|
|
This really make sense only when doing file I/O. @ On POSIX4-Unix, offset_high should be supported using aiocb64. Reimplemented from ACE_POSIX_Asynch_Result. Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |

Post <this> to the Proactor.
Reimplemented from ACE_POSIX_Asynch_Result. Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |
|
|
The priority of the asynchronous operation.
Reimplemented from ACE_POSIX_Asynch_Result. Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |
|
|
POSIX4 realtime signal number to be used for the operation. <signal_number> ranges from SIGRTMIN to SIGRTMAX. By default, SIGRTMIN is used to issue <aio_> calls. This is a no-op on non-POSIX4 systems and returns 0. Reimplemented from ACE_POSIX_Asynch_Result. Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |
|
|
Did the operation succeed?
Reimplemented from ACE_POSIX_Asynch_Result. Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |

The Proactor constructs the Result class for faking results.
Reimplemented in ACE_POSIX_Asynch_Read_File_Result. |
|
|
Message block for reading the data into.
